1. Point of the flip is to actually remove the heat pocket that normally sits in that zone, having a million fans in the front doesn't actually clear that zone as the video card creates a turbulent area and creates blockage. the PSU would have less heat on it by cycling out that area instead of having a stagnant zone. (not saying you have a million but the CFM balance in the region is pretty bad and as much as everyone likes to think their air channels in a straight line, it really doesn't so you need porting and exhausts in multiple zones where activity is high.

2. Probably do the front for the drives I'd say, no matter what you're going to lose a lot of pressure as it breaks around those and finds its way to the rest of the case, the bottom fan as long as it's not heavily obstructed would help channel it anywhere else you need.

3. You'd be surprised, a decent cool intake can deliver fresh current as your HDD and bottom intake will honestly do very little for that zone of the case.

4. If you only run positive pressure you're going to have heat issues still because you're not cycling out the heat from the system at all. You need more than just 1 exhaust and the PSU isn't going to remotely cut it for the entire system. I thought positive pressure was going to be awesome running 5 intakes and 1 exhaust but it was hell on my system in the summer. You need to match or at least get close with the CFM you're putting in and the CFM you're dumping out.

5. If the top fan is out of the picture, there really needs to be something behind that cpu cooler for the exhaust or you're doing it more harm than good. Otherwise it seems like a nice rig and yes I have worked in tight spots, the clips on the gelid are a nightmare and you can only install it with the fans off if spacing is also an issue you could always look into low profile fans as well.

Biggest thing is making sure your zones in the case get the right ventilation otherwise you're pretty much just relying on air currents to figure it out for you. The chamber smoke systems are a bit pricey or I would say use one of those to watch where your air current goes in the system. Either way you're not operating on negative pressure by any means, you'll have way more CFM coming in vs going out which means there will always be a point where the heat brews around components.

There is a fan on the back of the PC that is an exhaust. One issue I see with the top though is the two fans on the cooler are both PWM (the exhaust might be set up as one aswell), meaning just plopping a fan on the front would create a positive pressure system. The only way around that would either to run them all flat out or on a fan controller, or have the exhaust flat out and the intake and cooler fans on PWM to create negative pressure.

Even if there is a buildup up of air after the PSU is flipped, then how well would one of them PCI fans work? I know they're not big but I assume it's better than nothing. My main concern with that would be starving the GPU of air but that has two fans on so I guess it should be able to pull in enough on it's own.

Speaking about fans and shit. How do PWM splitters work? One of my CPU fans died and placed a case fan on it. So at the moment 1 of them, the one that's pushing air in, is the PWM fan and the 2nd one pulling is a 3 pin fan. Will the mobo read both?

I guess I'll try to order them PWM fans then. I was looking at the Cougar ones. Anyone had any experience with them? Not that expensive for PWM fans.

I'm pretty slow with these things so please excuse me if I sound dumb. If I connect the 3pin to the CPU header then all the mobo will do is read the RPM of the fan but not control it right? So if I would put the 2 fans with the molex instead, then they'll run at 100% but there won't be a way for me to control the speed. Now reason I ask, I looked at the H80 and noticed that the cooler has the molex and a 3pin connector. Does that mean that you manually control the H80 and the mobo is only reading the RPM?

Yeah, I've got an ingenious little PWM splitter that takes the power from the PSU direct, but has the PWM pin on to get a PWM signal from the board. Works like a charm since one of the CPU fan headers is inaccessible, and means I can have three PWM fans on one header.

Cable management cleanup might start today because the 24pin extension cable came earlier than I expected it to. Wasn't expecting it until Thursday... amazing since it's Royal Mail.

I guess the PWM fan goes connected to the 4 pin but what's getting to me is that I guess the 2nd fan which only has the 3 pin would be powered by the connection but wouldn't my readings be completely off? How I see it is that it's only being powered but not being controlled. So if the mobo decides to raise the speed when the CPU gets hot wouldn't that mean that the PWM fan will go up and the regular fan would stay the same right? Wouldn't that cause problems for fan 2?

I'm trying to avoid just plugging them all to the PSU through the molex. I don't want to have a lot of noise in the room really. These Cooler Master fans can get noisy.

harbin91, the extension you got is like those custom wired ones? I'm looking into getting a set for my PC. I like the BitFenix extensions. They're hot.

As a matter of fact, the extension is one of the Bitfenix ones. Since the wires are all seperate, it makes them easier to flex around. If I had the window case, and decided to go all out, then I would've scrapped all the cables that I had and gone for white cables with black connectors... just to match the front, and spent loads of money making the inside look nice. The other extension was an Akasa.

If a fan has four pins, then the last one (I think it is) carries the PWM signal. The splitter I have only carries the PWM cable on the fun pin header, so there is only one out of four pins. The only three fans I have on PWM is the rear exhaust (I believe, and the two fans mounted on the cooler.) If I go ahead with my case modding plan, the intake will probably be PWM and the rear exhaust will probably blow out on full.

EDIT: OMG THE SMELL OF NEWNESS. It's a corded fibre (feels like nylon anyway) casing aswell... it feels awesome. Looked on the back they have a largish range of colours aswell.

Man I want to get them now. I know NZXT has some also. But I don't know where I read that the BitFenix ones we're of a much better build. I also noticed on some pictures that BitFenix has the heatshrinks up into the actual connections. I like that.

Should remind me to periodically clean my intake dust filters... it was bloody horrendous. Sorted out my cable management, but decided to not flip the PSU, because of the hassle. The amount of mess I would've had to do to get the cables all neat and tidy would've made it impossible for me. Probably just me but my PC seems alot quieter, in fact its that quite it sounds like one or two of the fans actually aren't moving, even though I've checked them. Temps are slightly down but alot quiter anyway... and considering that it's 24.2°c in my room, quite happy with that.

Not sure where issues are in the airflow without getting one of them smoke machines, but instead of flipping the PSU, I might just get one or two PCI fans, to remove excess air and drag it underneath the GPU.

Still an issue with one cable... the power cable going from my PSU to my harddrives is simply too long. The gap is about 6cm yet the cable is atleast 15cm, and there is nowhere to actually put it except the unused HDD power connector sat on top of the PSU and the rest of the cable sat next to the side panel.... thing is, I can't replace it because I can't find any PSU/HDD cables anywhere. Got some photos, that I'll add to my thread anyway. To the eye there is a huge difference, but to the phone it doesn't seem like it.

I guess the PWM fan goes connected to the 4 pin but what's getting to me is that I guess the 2nd fan which only has the 3 pin would be powered by the connection but wouldn't my readings be completely off? How I see it is that it's only being powered but not being controlled. So if the mobo decides to raise the speed when the CPU gets hot wouldn't that mean that the PWM fan will go up and the regular fan would stay the same right? Wouldn't that cause problems for fan 2?

Decided to check out the actual PWM wiring, I thought the 12v itself was pulsed but it seems not.

The missing cable is sense, which reports RPM. The PWM is controlled by the fourth wire, control, so when you plug in a 3pin fan it will only connect to 12V and GND, so run at 100% regardless of what setting the PWM fan is running at.
